Definitions

  • the invention relates to cookware for an induction hob with at least one hotplate, the cookware having a container designed to hold food and/or food to be cooked.
  • Cookware with a contact section for making contact with an induction hob is known from the prior art.
  • the cookware is designed as a kettle with a container and is used to heat water.
  • the contact portion of the cookware is placed on one of the hotplates.
  • the corresponding hotplate of the induction hob is switched on by a user and the kettle heats up.
  • the water is warmed up or heated until the water boils.
  • the kettle has a temperature sensor, a control unit and a transmission device.
  • the temperature sensor detects this and the control unit activates the transmitting device, which sends a switch-off signal for the corresponding hotplate on the induction hob to a receiving device on the induction field.
  • An induction hob control unit then ensures that the hotplate on which the kettle is placed is switched off.
  • the disadvantage of this solution is that the kettle and the induction hob must have transmitting and receiving devices and therefore have a complicated and cost-intensive structural design.
  • the kettle can also be operated with an induction hob, which does not have a receiving device, but in this case the kettle would not switch off automatically and there is a risk that the kettle will overheat when the water in the kettle has completely evaporated.
  • a cookware which has a cooking plate which is directly connected to a lifting element.
  • CN 102 100 484 B discloses a cookware in which a cooking plate is pivoted on an axle, the axle being located on an inner bottom wall of the cookware. A lifting element of the cooking utensil is connected directly to the cooking plate.
  • WO 2016074743 A1 discloses a cookware having a cooking plate connected to a lifting member.
  • the cookware has at least one hotplate, which is arranged in the container so that it can move relative to the contact section, and the cookware has at least one actuator for generating a relative movement between the hotplate and the contact section, the actuator combining the hotplate and the contact section in one Operating position and in a rest position positioned relative to one another, wherein in the operating position the hotplate is inductively heated by the contact section of the induction hob, and in the rest position the hotplate is spaced far enough from the contact section that no induction of the hotplate through the induction hob contacting the contact section takes place, the structural design of the cooking utensil can be significantly simplified compared to the prior art because additional electrical components, such as a control unit and a transmitter unit for the cooking utensil, can be dispensed with.
  • the cookware can be used on commercially available induction hobs, in particular regardless of whether the induction hob used has a receiving unit for receiving switch-off signals for switching off the hotplates.
  • the cookware according to the invention is excluded in an advantageous manner that the cookware overheats, because as soon as a predetermined critical temperature is reached, the actuator moves the cooking plate away from the hotplate. Consequently, the hotplate is then arranged at a distance from the hotplate of the induction hob in such a way that overheating of the hotplate is ruled out. With the movement of the hotplate relative to the contact section, the hotplate can be easily brought into the operating position and heated inductively via the induction hob.
  • the hotplate With the positioning in the rest position, however, the hotplate is spaced so far from the contact section of the container that no relevant eddy currents are generated in the hotplate by the induction field contacting the contact section. As a result, no further heating of the cooking or cooking takes place when the hotplate is in the rest position.
  • the induction hob In the operating position, on the other hand, the induction hob generates eddy currents in the hotplate and heats it up so that the food to be cooked and/or cooked in the container can be easily heated.
  • the hotplate In the rest position, the hotplate is preferably spaced far enough from the contact section that the induction hob making contact with the contact section switches off automatically. As a result, when the predetermined critical temperature is reached, the cooking process in the cookware can be automatically terminated. As a result, no additional energy is consumed after the predetermined critical temperature has been reached.
  • the hotplate With the positioning of the hotplate by the actuator, there is an indirect coupling of the cookware to the electronics of the induction hob, which usually provides for the hob to be switched off when there is no longer any induction, since the distance to the inductively heated element is too great.
  • the hotplate is moved according to the invention so far out of the induction area that this is detected by the induction hob, which then automatically deactivates the hotplate.
  • the cooking utensil according to the invention can be realized exclusively with mechanical components.
  • the cooking utensil can be designed as a kettle, a pan, a pot, a tea maker, a wok, an egg cooker and the like.
  • the food to be cooked can be a mushy food or a solid food.
